Squishy Turtle - Narrow Head

Props to JakeJake for his Squishy Turtle and especially for his exacting tolerances - I have had to scale the bar on the head in order for it to print correctly. Noticing a lot of the comments on the original Squishy Turtle had the same problem, I have narrowed the sliding bar a bit to allow 3D printers with less perfect calibration to enjoy JakeJakes fabulous creation:)
